@Verpies, yes the nominal is only? 230 but most of time its 240 this is to allow electric companys to comply with regulations at peak demand.If I put meter on my mains lowest reading ever had was 236 at christmas time.

yes the nominal is only? 230 but most of time its 240 this is to allow electric companies to comply with regulations at peak demand.If I put meter on my mains lowest reading ever had was 236 at Christmas time.Let's use the nominal 230V voltage for our discussion, despite the allowable tolerance in UK being +10% and -6% which evaluates to a high limit of 253V and low limit of 216V.
So what is the nominal voltage from peak to peak of the sinewave in UK (measured between the neutral and any other three wires) ?
I claim that my original statement about this voltage is correct.?
Do you agree?? If not - what do you think is the nominal value of the aforementioned voltage?
@Verpies,you could be right,Wikipedia gives quite a good explanation on mains electricity.
Sorry took so long to answer, frost and flood at home to sort out.

This old diagram might help clean up some concepts for others:
In UK's power grid, the nominal voltages are:
A(max) = 325V
A(rms) = 230V
A(avg) = 207V
AP-P = 650V
T = 20ms
Also, it is important to remember that just because the power supply voltage is a sinewave with the above characteristics, it does not mean that the current flowing in a circuit connected to this power supply is also a sinewave.
In fact, the current waveform can have a completely different shape (a rectifier followed by a capacitor and a slight load, is a classic example of this).
Even if the current waveform is a sinewave, it does not mean that it has to be synchronized in time with the voltage waveform (zero phase shift).
A little trivia: Can any current flow in a circuit when the instantaneous voltage provided by the power supply is zero? (as illustrated at 180? in the diagram above).
@Verpies, I am playing with a huge 2ft by 1ft by1ft welding transformer and I can run a few 100watt bulbs by just turning on the variac to the trans about 1/4 inch so very high current and almost no voltage.When I get home at weekend I will check voltage and let you know.
